Objective:
The objective of this cooperative project is to maintain a FACE research site for investigating the effects of global change, including increased levels of atmospheric carbon dioxide, drought, temperature and ozone on soybean and corn.

Approach:
Free Air Concentration Enrichment (FACE) technology is used to mimic under field conditions atmospheric concentrations of carbon dioxide and ozone predicted for 2050. Crop canopy heating using arrays of infrared heaters are used in conjunction with FACE to mimic the effects of global warming under field conditions.
